Terahertz-Band MIMO-NOMA: Adaptive Superposition Coding and Subspace Detection
Hadi Sarieddeen, Asmaa Abdallah, Mohammad M. Mansour +2
We consider the problem of efficient ultra-massive multiple-input multiple-output (UM-MIMO) data detection in terahertz (THz)-band non-orthogonal multiple access (NOMA) systems. We…
Deep Learning Based Frequency-Selective Channel Estimation for Hybrid mmWave MIMO Systems
Asmaa Abdallah, Abdulkadir Celik, Mohammad M. Mansour +1
Millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems typically employ hybrid mixed signal processing to avoid expensive hardware and high training overhea…
Efficient Angle-Domain Processing for FDD-based Cell-free Massive MIMO Systems
Asmaa Abdallah, Mohammad M. Mansour
Cell-free massive MIMO communications is an emerging network technology for 5G wireless communications wherein distributed multi-antenna access points (APs) serve many users simult…
Power Control and Channel Allocation for D2D Underlaid Cellular Networks
Asmaa Abdallah, Mohammad M. Mansour, Ali Chehab
Device-to-Device (D2D) communications underlaying cellular networks is a viable network technology that can potentially increase spectral utilization and improve power efficiency f…
